      The chromomagnetic operator on the lattice 

      Constantinou, Martha G.; Costa, M. G.; Frezzotti, R.; Lubicz, V.; Martinelli, G.; Meloni, D.; Panagopoulos, Haralambos G.; Simula, S. (Proceedings of Science (PoS), 2013)
      We study matrix elements of the "chromomagnetic" operator on the lattice. This operator is contained in the strangeness-changing effective Hamiltonian which describes electroweak effects in the Standard Model and beyond. ...

      Renormalization and mixing in lattice QCD: The case of the chromomagnetic operator 

      Constantinou, Martha G.; Costa, M. G.; Frezzotti, R.; Lubicz, V.; Martinelli, G.; Meloni, D.; Panagopoulos, Haralambos G.; Simula, S. (2014)
      We study matrix elements of the "chromomagnetic" operator on the lattice. This operator is contained in the strangeness-changing effective Hamiltonian which describes electroweak effects in the Standard Model and beyond. ...

      Thermodynamic properties of QCD in external magnetic fields 

      Bali, G. S.; Bruckmann, F.; Constantinou, Martha; Costa, Marios Gil; Endrödi, Gergely; Fodor, Zoltán; Katz, Sándor D.; Krieg, S.; Panagopoulos, Haralambos G.; Schäfer, A.; Szabó, Kálmán K. (2012)
      We consider the effect of strong external electromagnetic fields on thermodynamic observables in QCD, through lattice simulations with 1+1+1 flavors of staggered quarks at physical quark masses. Continuum extrapolated ...
